FY 15 Rocky Mountain Region Maintenance Project s • New System Operation Methodology • Completed Projects • New Projects • Changed Projects • Ongoing Projects

Transmission Operator Methodology Changes • September 2011 Western grid outage • Revised System Operating Limit (SOL) Methodology-August 2013 – If the next single contingency will result in a voltage or thermal overload, PEAKRC requires pre-mitigation: • Load shedding • Generation curtailment (or increase); reactive device changes including generation redispatch • Reduction of scheduled power, may require purchase of power at spot market prices

Transmission Operator Methodology Changes • Western plans and designs its system to operate through a single contingency without loss of load (TPL standards). • Western Operations studies and controls the system to perform through multiple contingencies. (TOP standards) • Potential projects to address operational compliance standards – Curecanti 2 nd 230/115 kV transformer – Midway 230 kV bus configuration
